Estimate of molecular equivalents of antibody required for prophylaxis and therapy of poliomyelitis

Abstract

Calculations have been carried out which suggest that as few as 6 × 104 molecules of anti-poliovirus antibody per millilitre of serum may be sufficient to prevent the clinical disease under certain epidemic conditions. Other calculations have been made involving therapy of the experimental disease in monkeys and certain factors required for successful serum therapy have been discussed.
